Detailsinfo

A vulnerability was found in MyBB 1.4.10 (Content Management System). It has been classified as critical. This affects some unknown functionality. The manipulation of the argument avatar with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality. The summary by CVE is:

Directory traversal vulnerability in MyBB (aka MyBulletinBoard) 1.4.10, and possibly earlier versions, when changing the user avatar from the gallery, allows remote authenticated users to determine the existence of files via directory traversal sequences in the avatar and possibly the gallery parameters, related to (1) admin/modules/user/users.php and (2) usercp.php.
